This post isn't directed at your comment Jean; it's been on my mind for quite some time and obviously others are thinking it too.

I don't understand the hoopla over this bicyclist. It's a given that exercise helps. Everyone in the world is supposed to exercise vigorously. Some do, some don't. Why must we spend money on researching this? The outcome will be that it helps to exercise. Are they going to give everyone a bike after the study? How is this research going to benefit pd patients?

Wouldn't the money be better spent developing exercise classes and equipment?

Adding that i am aware of the curiosity about why he can ride the bike but can't walk. There are many examples of things pwp can do that defy their other symptoms. Why are we waiting for curiosity to be satisfied if it isn't going to lead to any benefit?
